` GRAFTING.

To all whom it may concern: A

Be known that l, Roni-arr C. llifm', a

eitixeii of the yUnited States, residing atv llortoiis. inthe county of lndiaiia and Statt-L n ot' lennsylvaiiia, have invented new and useful.lniproveinents in t`xi`i"tin;, ,y of which the tollowing` is a spetitieat'ioii.l

rlh'is invention relates to certain new and useful improvements in graftingc'; andv relates more particularly to grafting of trees and Similar growths. l

The object. of the invention is to provide an improved means of forming the graft. lock or joint between the Scion and the stock. Y

The invention further aiiiis to provide a. joint,V or loek of this type which will be sini'ple and susceptible ofheing formed with out the aid of special tools or :1 pliaiices.

Further and other objeetswil later ap;-l

pear and be set forth.

1n the drawings Figure l is a view in perspective of the invention. Fig. Q is a iaginentaiftf 'vertical seetionalview of Fig. 1, l"ig.,3 is a transverse section on the line the line. 4-4of Fig. 2, Fig. 5 is a perspective view of the stock.' Fig. t3 is a front elevation of the seion. as used iii a modified form of the invention. Fig. 'i' isV a view similar to Fig. 2 of a slight modification, Fig. 8 is a transverse set-tion on the line S-S of Fig. 7, Fig. 9 is'a similar view on the line 9-9 of Fig. 7, and' l"if. l0. is a perspective view of the seioii employed in the inoditicd form.

'lhe stock is depicted in the drawings as being L`-;irnied with a cleft which tapers from ttm tt. bottom. tlnie elel't being fol'iiietltf two side walls 1 and i. which foi-in a Vshaped space between them. 'l`lie rear wall Il' inelines downwardly niitily it meets the walls 1 and 2 at a coiniwii point L It will be seen that thc waits l and 2 forni a V-shaped space in front elevation and in cross section forni a wedge shaped or a V-sliapcd spat-e as iii-ll. 'l`he seion 5 in front elevation is of Lsliape and in its transverse scction is shaped to be eonformably received in the elett. lthe front side of the scion, as shown in the drawings, lying flush with the bark of the treeor the like and its rear face or side beiig arranged in spaced relation to the wall f5 provided by the cleftso as to provide a passage or channel 7 which at one end communicates with the atmosphere at; z

communicates wit-li the atmosphere at. points between the lowest end of'tlnlrscion and the lowest end of the cleft in thel stoel..

ln the-modified form of the invention the cleft lt in cross set-tion has its walls 1l and l2 at a less acute angle to veachother than in the other forni of the invention. The rear wall 13 tapers in a manner agreeing with that' of the rear wall 3 in the preferred 'foi-m. It will be noted however., that. in this forni of the invention the walls 1l and 1Q in front` elevation do iiotincline toa sharp point as in the preferred form, but on the contrary meet at a bottom wall ,14 which between the. upper end of the walls 1I and .12. The scion 15 as depicted in the draw- 't iiigs is 'liaped int-his forni of the invention to he. eoiiforinably received in the cleft. l0

t and has its rear side 16 spaced fi'oni the rear v wall 13 of the cleft so as to form a passage of the stoe-k to the wall 14.

lt will be understood that in' vpractice grafting wax is used as is common. It will be seen that a neat jointy is thus provided and one which is extremely lellicient in practice` The scion '1s inserted into the elett of the .stock by plaeing the lower end of the scioii in the cleft. and then moving the entire seioii downwardly. wedging its walls into engagement with the walls of the cleft, thereby forming a neat, seeare andaeenrate union between the stock andl the srion.

As is well known, the sap flows at points periphery of the tree body. By reference to Figs. 3 and 8 of the present ease it willbe seen that the. cleft. and the stok-k are so proportioned that the bark on the selon and v ont the length of the seioii` thus plaringthe l flows in the steek, which is a feature of great importance and advantage since it thus plziees the seion in position where it reveeives the greatest nourishment and benefit from the sap of the stoelt. 'lbus the sap will course from the stot'k through the Seion both transversely and longitudinally of the latter.

'hat. is elaiiied as new is:
